CAR-COUPLING.

SIPECIFICATION forming part of Letters Patent No. 576,094, dated February 2, 1897. Application filed September 2, 1896. Serial No. 604,615. (No model.)

To all whom it may concern:

Be it known that I, HENRY DEITZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Oar-Couplers, of which the following is a specification.

My car-coupler relates to that class known as the Master Oar-Builders standard of vertical-hook type and my invention has for its object to provide means to throw open the knuckle simultaneously with the movement which unlocks the knuckle and to do this with the locking-piece in the simplest and most efficient manner.

Reference will be had to the accompanying drawings, in which--- Figure l is plan sectional view through the coupler. Fig. 2 is a vertical sectional View on line 2 2 of Fig. 1. Fig. 3 is an end vertical sectional view on line 3 3 of Figs. 1 and 2. Fig. 4; is a perspective view of the lower end of the locking-pin. Fig. 5 is a perspective View of the end of the knuckle which comes into engagement with the looking=pin. Fig. 6 is a similar plan View to that of Fig. 1, showing the locking-pin in a different position. Fig. 7 is a similar view to that of Fig. 2, showing the locking-pin in a different position.

Fig. 8 is a similar view to that of Fig. 3 with the locking-pin in the position shown in Figs. 6 and 7.

In the drawings, A designates the ordinary main cast piece of car-couplers of this class, and B designates the knuckle thereof.

D is the locking-pin, which is made in a manner to serve the purpose of automatically locking the knuckle and also to throw open the knuckle when the pin is lifted, as will be described. This pin D has a slot d in its forward edge, (shown by the dotted lines in Figs. 3, '7, and 8,) which engages a projection E in the front wall of the main casting. This slot cl is inclined and offset at its lower end, as is shown in Figs. 3 and 8, for the purpose of throwing the lower end of the pin at an incline when the pin is lifted, whereby the shoulder D of the pin engages a lip B of the knuckle end, as is shown in Figs. 6, '7, and 8. The purpose of this is to provide that when the locking-pin is lifted and let fall back again before the cars are pulled apart, permitting the knuckle to be opened, the pin will fall back and rest upon the end of the knuckle andride thereon until the knuckleis pulled open, whereby the pin rides off the knuckle end and drops in its normal position ready to couple automatically. The pin when down in its normal position, locking the knuckle, is shown in Fig. 2, and when in this position and the knuckle is open and a coupling is made the pin swings back, to free the end of the knuckle, to the position of the dotted lines in Fig. 2, the lip L of the pin engaging the projection P of the main casting, and thereby acting as a center about which the pin revolves when automatically coupling, and when the knuckle is home the pin swings back to its normal vertical position between the end of the knuckle and the side wall of the casting, thereby locking the knuckle.-

On the lower end of the pin D there is a projection D having a lip D and the outer end of the knuckle is cut away on an incline, as is shown at 13 which leaves an inclined way B and upon the lifting of the pin forcibly the inclined slot at throws the lip D into engagement with the inclined way B (see Figs. 7 and 8,) whereby the further upward movement of the pin, the lip D engaging the way B by virtue of the incline, forces the knuckle end outward and open in the position of the dotted lines in Fig. 6, provided, however, the knuckle is free to open, not being in contact with any other coupler. The purpose of this means of throwing open the knuckle is to avoid the necessity of the brakeman entering between the cars at any time for any purpose when coupling, and should he find the knuckle closed when he desires to couple all that he is required to do is to lift the cutting-out lever, thereby lifting the locking-pin, which unlocks the knuckle and throws it open by the vertical movement, as above described, and this means of throwing open the knuckle is secured by the simple addition of the end-projection lockingpin and by the cutting away of a portion of the end of the knuckle, making no new part to the coupler nor adding any additional eX- pense in its construction, which is a great desideratum. v

\Vhat I claim is- 1. The combination with a draw-head and a I horizontally-swinging knuckle pivoted therein, of a vertically-movable locking-pin normally obstructing the path of said knuckle, but not when partially raised, devices Whereby the pin if partially raised while the knuckle is closed is prevented from automatically descending until the knuckle opens, and means whereby completing the raising of the pin throws the knuckle open.

2. The combination of a vertical lifting locking-pin, of a lip on the lower end thereof, of means for inclining the lower end of the pin when the pin is lifted, whereby the lip on the end of the pinis swung underneath the end of the knuckle, with an inclined way on the end of the knuckle-piece for the purpose of being engaged by the lip on the pin whereby the knuckle is thrown open as described.

3. The combination of a Vertical lifting locking-pin, of a lip on the lower end thereof, of a slotin the body of the pin engaging the projection on the main casting of the coupler, the lower end of said slot inclined as described, for the purpose of inclining the bot tom of the pin, with an inclined way on the end of the knuckle-piece adapted to be engaged by the lip on the lower end of the pin whereby the knuckle is thrown open, substantially as shown and described.

In witness whereof I have hereunto subscribed my name, in the presence of two subscribing witnesses,on this 19th day of August, 1896.
